I need to get a new cartridge. Don't know the mass of this arm. Trying to figure out a matching cartridge. The specs for the arm don't give the mass of the arm. Anyone have any ideas?
Figure the MMT arm as a medium mass arm and you should be fine. Cartridges that want to track at the upper end of 1-2 grams should work with this arm. Buy a medium-high compliance design. Depending on the table this will mate with, I would start by looking at the Grado line.
